Split Dagger of Janus

The Split Dagger of Janus is a holy item in the Two-Faced Cult, used primarily for rituals like the Splitting of the Self.

Properties

The original Split Dagger of Janus is a Mightem, a blessed item imbued with the duality domain of Janus.
The blessing gave it a magical property that can split anything into two identical halves of itself, fully functional, yet separate parts of the whole that must be joined back together to return to their original state. It also works on spells and all forms of matter. This blessing is not always active, and can be turned on and off so that it may instead be used for rituals.
The original has a metallic silver hilt with purple and white striped cloth wrapped around it, with the blade then splitting off into two blades that reach outwards from the one side of the hilt in a v shape, both made of the same metallic silver as the hilt and both sharpened to a point that they could pierce and cut with ease.

Recreations

While it is not clear where the original is, anyone can recreate the dagger under the right circumstances if they need it.
Not all recreated Split Daggers need the same colors or materials, but they do need the exact v shape of the blades connected to one hilt. Aside from that, they can be personalized, with a popular color for the hilt being pink, white, and blue.
Anyone can forge a Split Dagger, but once it is forged, it must be blessed. To bless a Split Dagger, it must be placed in a doorway and left for two weeks, with no one passing through the door nor disturbing the dagger in its place of rest.

Janus

Janus is the God of Portals, Duality, and Transitions, and oversees all people at a crossroads in life, as well as any time the world is entering a period of transition.
On a smaller scale, people coping with change pray to Janus in hopes that they may one day accept or find comfort in it.

Once it is gathered again after the two weeks, it will have the blessing of Janus and may be used for rituals. This blessing does not give it the enchanted property of the original, but allows it to be used for any symbolic purpose that the original would have as an important holy item.

Utility

There are many potential uses for the Split Dagger, both the original and any recreations, as it is a treasured relic of the Two-Faced Cult.

Ritual Use

The most well known ritual to use the Split Dagger for is the Splitting of the Self, where one makes a small incision down the center of their body to commune with a part of themselves that they need to accept.
For this, and other rituals, one blade is for the initial cut, the other is for the remainder of the process.
In many other rituals, the dagger must be properly cleaned, then covered in holy oils to give it a non-magical blessing. The blessing, then, helps the ritual to proceed as Janus would intend, be it for ceremonies like marriage or funerals or whatever other crossroad of life a ritual of Janus helps someone to get through.

Non-Ritual Use

Outside of rituals, it can be used for anything that whosoever wields it decides it could be used for. It can serve as a weapon, stabbing an enemy twice or two enemies at once. It can serve as a defensive tool, cutting apart magic into two halves that would then dodge around the initial target of the spell.
It can even be used to cut and eat food, splitting it into pieces like any knife would but ensuring that the pieces are equal in size and therefore equal in taste from one to the other. A proper meal is made when a Split Dagger of Janus is used.
Some outside of the Two-Faced Cult consider these uses disrespectful, but Janus has said of it:

"Respect is a phrase tossed around by those with nothing respectable about them. I call my followers a cult because I have no need for respect, just the wellbeing of the world and its people and continued fun for myself. I couldn't care less what someone does with my holy items, as long as they treat themselves well and as long as they are doing what they can to help themselves and others."
